IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 132,477, dated October 22, 1872 To all whom it may concern:

Be it known that I, JOHN E. LONERG-AN, of Sacramento, Sacramento county, State of California, have invented an Improved Lubricator; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

My invention relates to an improved oil cup or lubricator for journals and other frictional surfaces, and is particularly adapted for use on locomotive-engines.

In order to explain my invention so that others will be able to understand its construction and operation, reference is had to the accompanying drawing forming a part of this specification, in which- Figure I is a vertical sectional elevation.

A represents a cup, which, in the present instance,is composed of an outer skeleton metal frame and an inner glass vessel, so united together that the oil will be held inside of the glass vessel without leaking. The stem B, which extends downward from the 'center of the bottom of the cup, has a hole passing through it, the upper end of which, where it opens into the cup, is made conical. A' spindle, 0, passes down through the center of the upper end of the cup, and has at its lower end a conical plug, d, which fits into the conical hole in the stem B, so as to completely close the hole, where it is allowed to freely rest in it but by slightly elevating this stem a space will be opened entirely around-the plug, through which the oil will flow and drop from the 1 point or apex of the cone corresponding in quantity to the size of the opening. A hole, Z, in the top serves as a vent. A spiral spring, h, is coiled around the spindle so as to bear at its lower end against the enlargement of the upper end of the cone. The upper end 6 of the spindle O is somewhat enlarged, as shown at Fig. 1, and is made to fit closely in the hole in the center of the upper end of the cup through which it passes. A small horizontal thumb-wheel, d, is formed the cup, as by depressing the valve) the oil can be poured directly into the upper end of the hole, through which it will pass into the cup. The spring 9 keeps the valve tightly closed and prevents the entrance of dust into the cup; it also prevents the oil from being thrown out of the cup by the motion of the engine or piece of machinery upon which it is fixed.

In order to regulate the feed of the cup I employ a vertical set-screw, j, which passes down through the rim of the thumb-wheel d,

and which can be fixed at any desired pointby a locking thumb-screw, k, or other equivalent device; 0n the upper end of the cup, in

a position to receive the lower end of the screw j, I secure a projection, m, which has a depression in its upper face. By turning the spindle the set-screw j can be brought direct- 1y over this projection, when, by turning the screw down so that its lower end will rest in the depression or concavity in the upper face of the projection, the spindle can be raised, as desired, so as to lift the conical plug d and allow the oil to feed out through the stem B.

When it is desired to cease feeding the oil it is only necessary to lift the spindle and turn it slightly, so as to let it descend without allowing the screw to rest upon the projection. This allows the plug d to completely closethe feed-opening, and when it is desired to again feed the oil it will only be necessary to lift the spindle and turn it until the screw rests on the projection, and thus preserve the exact quantity of feed which was previously had.

Having thus described my invention, what Y 2 new? I claim, and desire to secure by Letters Patthe parts and opera-ted in the manner above ent, is described.
